Abstract (en)
A lighting device is provided that includes a light source and a plurality of polymeric side-light guides. Each of the polymeric side -light guides has sides, a first end, a second end, and a side contact edge. Each end has a surface that defines a cross-sectional area. The ends of the plurality of polymeric side -light guides fit together substantially without gaps between the polymeric side-light guides to form a first surface. The total cross-sectional area of the first surface of the plurality of polymeric side-light guides is substantially equal to or less than the cross-sectional area of any of the surfaces of the second end of any one of the polymeric side-light guides. The light source is configured to inject light into the plurality of polymeric side-light guides through the first surface. A kit and method for assembling the kit are also included.
